Should I stay...?

My boyfriend and I have had a hard time lately..not in the sense that we’re fighting or anything but he got into a little trouble with the law and might go to jail next month 😰 It was a stupid mistake but he’s been extremely down in the dumps and kinda withdrawn from me. We’ve just started TTC 2 months ago and there’s a definite chance I’m pregnant right now but to early to test(11 DPO). I really love him and I know in my heart he loves me but he’s making life really difficult lately...like getting drunk. I’m not a drinker at all so I feel like I’m making it out to be a bigger problem than it is.

I’m starting to get scared though if I am pregnant and he goes to jail I’ll have to do this on my own 😔😭. I genuinely want to stay but should I? Is this a healthy environment for me being pregnant?
